If you follow this link, I need someone to write up a better solution than this one because I feel it has skipped to much and I don't understand it!

Thanks in advance!

The series in question is here:

Please tell me which test you used to determine your answer. Also, I tried the alternating series test and I got that it is decreasing for all x > e^2, and the limit as n -> infinity is zero. I'm not sure if the decreasing for x > e^2 means the sum is finite or not, since its not for all x > 1.

This is a question for college professors/ grad students. I'm looking to get a few different books that detail successful writing habits across different genres. For example, how to write an essay, how to write an open letter, how to analyze a documentary. Really I'm open to any book that you think would be beneficial in teaching successful writing habits. All recommendations appreciated, reasons would be great as well.

I have worked on this one for awhile, but I can't seem to figure it out. I've tried integration by parts, changing it to sqrt(sin(x))/sqrt(cos(x)), and a few other things.

Integral of sqrt(tan(x))dx is the problem. & I would appreciate thorough work so I can learn.

integral from 0 to 1 of (1-x^(7))^(1/3)-(1-x^(3))^(1/7)

To clarify. I need to know why the answer to the above integral is equal to zero.

I can see from a graph that the two functions area's are equal from 0 to 1 therefore subtracting them will yield zero. This will not suffice however, as I need a more mathematically rigorous answer. Also, I am almost positive that directly integrating them isn't necessary as I don't think they even have closed form integrals.

So I'm looking for a decent mathematical explanation (not geometrical) that doesn't use too much super advanced stuff!

**Note, I believe I am to take advantage of the fact that they are inverses??

** Or perhaps use the substitution U =1-x^7 to integrate

These are just ideas, I'm not sure it helps.. I can't seem to work through this one...

The centers of two circles having radius 1 are one foot apart. Find the area of the intersection of the two circles..

I need a thourough explanation please, with each step.. Trying to study for test..

Ok my question is based on these two functions

e^(sqrt(x)) AND e^(x^(2)) so e to the sqrt x power and e to the x squared power.

Why can I use u substituion with the first function (e^(sqrt(x)), but not with the second one? I don't see how we have the du for either of them.

For the first one we certainly don't have a 1/sqrt(x) and for the second one we don't have the x (2x if you want)

Anyone who explains this well is doing me a HUGE favor :) Test soon haha

Is there a need to intiliaze a pointer to NULL in C? To elaborate:

int *ptr = NULL;

int *ptr;

Are these two lines equivalent?

integral of 1/((s^2)*(s-1)^2)

My algebra is a bit rusty, can someone explain how to get the A, B, C, and D coefficients. usually I just plug in the zeros and kill the other terms, but in this case A and C have the same factors and I don't know how to find them..

Thanks.

Can anyone name movie's that have robbery scenes featuring lasers? Like ones were someone is trying to steal something and they have to manuever their way through a bunch of criss crossing lasers.

Integral of (1-cos(4x))^(1/2);

Honestly I can't figure this one out. It's the last one I have left to do, but I don't know how to handle it. I've tried different combinations of the double angle formula, but I cant seem to figure it out. Help would be great. Honestly if you just give me the path to follow, I think I can do the math on my own

---DISCLAIMER--

NO trig substituion for this problem. So please do not include it in your answer
